Working Group on Measurement of Fuels

Terms of Reference

BACKGROUND
The Working Group on Measurement of Fuels (WG-MF) was established in 2021, and formed in 2022. Formation of the Working Group formalised a stream of fuel measurement training activity that had operated within APLMF for many years. It is recognized that the scope of measurement of fuels is broad, covering a range of fuels and various measurement methodologies. It is also a dynamic area of measurement that includes emerging fuels, measuring instruments, and techniques, such as measurement of hydrogen, for example.

SCOPE
The scope of the WG-MF includes dynamic volume and mass measurement for fuels. This scope includes a range of fuel types and measurement (proving) methodologies. Fuel types are petroleum in liquid/gas and related products, including:
• Crude oil
• Liquid hydrocarbons
• Liquefied petroleum gas (LPG)
• Liquid fuel, lubricants, industrial oils or bunker fuel
• Liquid natural gas (LNG)
• Compressed gas (compressed natural gas [CNG] and hydrogen).

Measurement of these fuels is covered by OIML R 117 Dynamic measuring systems for liquids other than water and R 139 Compressed gaseous fuel measuring systems for vehicles.

The scope of the WG-MF does not include water or other liquids covered by OIML R 117 such as liquid food, alcohol, ‘special water’ or other liquids not listed.

A range of measurement (proving) methodologies for fuels are covered by the scope, including:
• Volumetric methods using volume provers
• Volumetric methods using master meters
• Mass flowmeters
• Gravimetric methods.

The scope does not include measurement of fuel quality. It also does not cover static volume and mass measurements related to fuel, such as:
• Fixed storage tanks (OIML R 71)
• Road and rail tankers with level gauging (OIML R 80)
• Automatic level gauges for measuring the level of liquid in stationary storage tanks (OIML R 85)
• Ships tanks (OIML R 95)
• Measuring systems for the mass of liquids in tanks (OIML R 125).


OBJECTIVES
To harmonize the requirements for fuel measurement in the Asia-Pacific economies with a view to removing technical barriers to trade.

TARGET OUTCOMES
​To build capability in measurement of fuels included in the scope of this document across Asia-Pacific economies. Capacity building may include, but not be limited to, delivery of training courses, workshops or seminars.

Current Work Programme 
The current work program is focused on delivering a training course on verification of fuel dispensers.
​
Additional training programs will be organised and delivered as identified by member economies and on an as-needed basis.

History

  • 2021 – Working Group was formally established
  • 2022 – Membership was formed
 
NOTE 1: WG-MF covers measurement of volume, mass and flow rate of fuels (liquid petroleum and gases) for the purposes of legal metrology. Working standards for fuels, such as capacity measures and provers, are also included
